[0002] Mechanical oil recovery is currently the most important method of oil recovery, and the walking beam pump is the earliest and most commonly used pump. Its working principle is that after the motor is decelerated by a V-belt reduction box, a crank rocker mechanism converts the rotational motion of the reduction box output shaft into the reciprocating motion of the walking beam donkey head.

[0003] Publication No. CN211397545U discloses a tower-type double-well pumping unit, which controls two oil wells to work simultaneously through one motor, avoiding the need to set up a large number of ground facilities at the wellhead of the oil field. This can effectively solve the high cost of ground facility construction and the problem that one oil well is not restricted by the maintenance of the other oil well when producing oil, thereby improving work efficiency. However, this patent still has the following problems in actual use:

[0004] Although this tower-type dual-well pumping unit controls two oil wells to work simultaneously through one motor, avoiding the installation of a large number of ground facilities at the wellhead of the oil field and improving work efficiency, it also increases the load on the motor and is prone to burning the motor under high-intensity working conditions.

When the handle is not subjected to external force, the restoring force generated by the deformation of the first spring is used to drive the handle to move around the limiting column, so that the two semicircular balls are in an inclined state, which can limit the first fixed block and the second fixed block, and the aluminum heat sink can be installed on the surface of the switched reluctance motor;

[0021] 2. By setting up a clamping mechanism, the switched reluctance motor can be quickly disassembled and assembled for maintenance without using any tools. By pressing the push rod inward to move it in the through hole and compressing the second spring at the same time, the limit of the push rod on the steel ball is released, and the steel ball can fall into the through hole, thereby releasing the limit of the steel ball on the limit groove, and the lower shell and the upper shell can be separated, which is convenient for the maintenance of the components of the switched reluctance motor.
